The read check of the above inputs and the interruption check
of CS, CI, and CD are performed.
In the read check, ER and RS are changed over in the above
sequence and the logic states of DR, CI, CD, and CS are
checked.
If the logic differs from that in the table, an error display is
made.
"ON" in the table means Active LOW, and "OFF" means Active
HIGH.
In the interruption check, an interruption of CS, CI, or CD is
allowed one by one. (MASK is canceled.)
If an interruption is not made when each signal is active, or if
an interruption is made when each signal is not active, an error
display is made.
The above check is repeated four cycles.
•
Data transfer check
The loop back data (256 bytes) of 00H
∼
0FFH are used for
data transfer check. The baud rate is set to 38400BPS.
•
Timer check (RS232 on board timer)
Before performing the check, set the timer to TCVDT start and
5ms. Then perform the following procedure.
*
During execution of the check, TRQ- must not be
